A kind of storage battery that has acid filtering structure

Technical field

The utility model relates to battery technology field, relates in particular to a kind of storage battery that has acid filtering structure.

Background technology

Lead acid accumulator (Lead-acid battery) is a kind ofly mainly by lead and oxide thereof, to be made, and electrolyte is the storage battery of sulfuric acid solution.Under state-of-charge, anodal main component is brown lead oxide, and negative pole main component is plumbous; Under discharge condition, the main component of both positive and negative polarity is lead sulfate.

Lead acid accumulator is chemical energy directly to be changed into the device of electric energy, is by the battery of rechargeable design, by reversible chemical reaction, is realized and being recharged.Its operation principle: utilizing outside electric energy to make the regeneration of inner active material during charging, is chemical energy electrical power storage, again chemical energy is converted to electric energy output in the time of need to discharging, such as motorcycle battery conventional in life etc.

Storage battery for motorcycle can be divided into plain edition and valve control non-maintaining type.Lead acid accumulator forms by positive/negative plate, dividing plate, housing, electrolyte and wiring pile are first-class, the chemical reaction of its electric discharge is to rely on positive plate active material and positive and negative pole active matter to carry out under the effect of electrolyte (dilution heat of sulfuric acid), and the grid of plain edition accumulator plate is to manufacture with lead-antimony alloy.Non-maintaining type storage battery is to manufacture with lead-calcium alloy, because having adopted lead-calcium alloy, storage battery makees grid frame, so the water decomposition amount producing during charging is few, water evaporation quantity is also low, add that shell adopts valve-control sealed structure, the sulfuric acid gas discharging also seldom, so it is compared with plain edition storage battery, have and do not need to add any liquid, the advantage such as non-maintaining.

Plain edition lead acid accumulator, in use, water decomposition or evaporation form acid mist, the acid mist filtered of overflowing is directly discharged, corrosion surrounding devices, contaminated environment, due to the continuous evaporation of moisture, need to often add water storage battery is safeguarded simultaneously, maintain the density of electrolyte.

Utility model content

For solving the direct problem of discharge of acid mist in plain edition lead acid accumulator for existing motorcycle, it is a kind of rational in infrastructure, simple and practical and have the storage battery of acid filtering structure that the utility model provides, and can absorb the acid mist in institute's Exhaust Gas, prevents the pollution of environment.

A kind of storage battery that has acid filtering structure, comprise the battery cap with air-vent, the top of described battery cap has the air channel of arranging along battery cap length direction, described air-vent is distributed in the bottom of air channel, at least one side of described battery cap is provided with the steam vent being communicated with described air channel, and the joining place of steam vent and air channel is placed with filter acid film.

The problem of directly discharging for solving acid mist, the utility model arranges filter acid film at the joining place of steam vent and air channel, to filter the acid mist producing in battery use procedure, prevents that acid mist from overflowing and corrode surrounding devices, protection of the environment.On battery cap, have a plurality of air-vents, each air-vent is corresponding with electrolysis tank, for water electrolysis, produces gas purging, and gas or the acid mist of discharge are discharged by steam vent after air channel.

As preferably, the top seal of described air channel is combined with sealing plate, described sealing plate bottom surface convex with the lead corresponding with described air-vent position.

Sealing plate also has the acid mist of preventing and is directly discharged into airborne effect, and produced simultaneously acid mist condenses on sealing plate, and the water droplet of formation can fall after rise to corresponding electrolysis tank by lead, reduces the loss of water, reduces the frequency of maintenance of battery.

As preferably, the cross section of described lead is herringbone.

Conventional lead is cylindrical structure, for accelerating condensing of acid mist, cross section that can also lead is set to herringbone, and described herringbone is comprised of three blocks of plates radially, with this, increase the contact area of acid mist and lead, further reduce the loss of water.

As preferably, in the air channel between adjacent two air-vents, be provided with dividing plate, between the edge, top of described dividing plate and sealing plate, be exhaust passage.

Dividing plate makes each air-vent have the air channel space of isolation, after the acid mist that each air-vent overflows condenses, can fall after rise to electrolysis tank, keeps the loss of each battery case water even, and the water that adds that is beneficial to storage battery is safeguarded.

As preferably, the air channel inclined bottom surface that each air-vent is corresponding arranges, described air-vent is positioned at the lowest part of bottom surface.

The air channel bottom surface being in tilted layout is beneficial to the drop condensing and falls after rise to electrolysis tank, can prevent that drop is accumulated in air channel, also has the effect that reduces damage by water consumption.

As preferably, described steam vent is arranged along described battery cap length direction.

Preferred side by side, described battery cap one side convexes with the exhaust nozzle of vertical layout, and described steam vent is positioned at the bottom of exhaust nozzle.

Steam vent has two kinds of arrangements, and the first steam vent is opened in battery cap sidewall, and arranges along its length, and the second steam vent is arranged on the exhaust nozzle bottom that battery cap side protrudes; The arrangement of steam vent can be selected according to the concrete service condition of storage battery by producer, also can two kinds of employings simultaneously.

The utility model is rational in infrastructure, simple and practical; Utilize filter acid film to filter acid mist, prevent the direct discharge of acid mist, protection storage battery surrounding devices and environment; And changed the exhaust structure at battery cap top, and realize the backflow of condensing of steam, reduce the loss of water, reduced and added the frequency that water is safeguarded.
